Replace worn or missing quick release pins. These are the same pins included in the Deluxe Weight Bag Kit (Part No. 5425) and Heavy-Duty Stake Kit (Part #5415), but they have many other uses around the paddock and trailer. These 1/4" diameter pins are a great choice wherever a secured quick-release pin is needed, but the precision and strength of a Pip Pin would be overkill. Grip length 2.5".
